Facts

Interesting Facts
  • Yttrium Metal is highly toxic.
  • Yttrium Metal is highly reactive in nature hence not found free in nature.
  
  • Aluminum’s abundance percentage is more as it is found in more than 260 minerals.
  • Pure Aluminum always reacts with oxygen rapidly.
  • It is a good conductor of heat and electricity and used in transmission lines.
